Acryla Designer Gouache is a fast-drying, opaque acrylic based watercolor paint. It's water soluble while wet, and water-resistant, matte and opaque, even over dark surfaces. Great for grounds and layering.
Color Swatch created using full strength/50/50 and was applied on cold press Bristol board (2 ply) material.
Fluorescent pigments such as BV11:1 offer intense and brilliant effects because they absorb ultraviolet light and re-emit light at longer wavelengths.
Like all fluorescent pigments, BV11:1 is not considered permanent. It will fade with exposure to ultraviolet light.
organic, fluorone dye
Rhodamine 6G is a staining reddish-yellow pigment that has fluorescent properties. It is extremely soluble in both water and alcohol. Fluorescent molecules absorb light at one wavelength and emit light at a longer wavelength.
Rhodamine 6G, like all fluorescent dyes, is not considered permanent, however it is reported to have high stability for a fluorone dye.
Rhodamine 6G is toxic, however it can be biologically inactive and hence non-toxic in a lake pigment form.
Rhodamine dyes are often used for microscopy in the biological sciences.
